Biology: Vickery stated: "Field observations indicate that P. poiformis occurs only in sites adjacent to the ocean and estuaries where it is under some degree of influence of salt spray. From the landward side P. labillardieri approaches and may even intermingle with it. I have usually had no difficulty in distinguishing them in the field by the smoothness and slightly greater succulence of the leaves of P. poiformis and its more dense, contracted panicles with usually rather larger spikelets and lemmas and rather rougher lemmas". She considered that herbarium material could occasionally not be identified. There are specimens in AD from Mount Lofty identified by Vickery as P. poiformis.
